AUTOMOBILE LOCK.

Application filed February 11, 1924. Serial No. 692,009.

To all whom z't may concern.'

Be it known that I, WILLIAM F. Lawson,

a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of IOhio, have invented certain new and useful Improvements in Automobile Locks, of which "the following is aspecificatlon. n

rllhis invention relates to improvements in automobile locks having for an object to provide a simple and etcient means to prevent flow of fuel to the power plant of the automobile.

Another object is to provide a double locking means whereby to prevent manipulation of a fuel control valve by unauthorized persons.

@ther objects will be in part. obvious and in part pointed out hereinafter.

lln order that the invention and its mode r of operation may be readily understood by persons skilled in the art, l have in the accompanying illustrative drawings and in the.

following detailed description based thereon set out one possible embodiment of the same.

ln these drawings:

Fig. 1. is aside elevation showing my improved locking device in use;

Fig. 2. is a top plan view thereof;

Fig. 3. is a horizontal section taken on a plane slightly below the center;

Figa/l. is a sectional view taken substantially on the plane ot d-ll of Figure 5; and

F ig 5. is a view showing the position of parts prior to assembly.

Having more particular reference to the drawing throughout which similar character's of reference designate similar parte this improved automobile lock may be broadly stated as comprising the positioning or a control valve in the fuel line preterably adjacent the carburetor and arranging thereover a two-part shell or casing which is securely locked in place in such a manner as to prevent unauthorized operation of the valve.

l/Vhile other designs of valves may be employed, ll preferably use a three-way type, two branches of which are arranged to conneet in a straight line the i'uel supply pipe 6 and the carburetor connection 7 while the third branch is open. and extends laterally away from the engine body and carburetor as is obvious.

This third branch is arranged to permit of connection thereto an air pipe or air pump by means of which the carburetor or the fuel line 6 to the supply tank may be rgleldily cleaned, simultaneously or individua y. v

The Irotatable valve 8 as shown is prefer- .A

ably provided with an operating linger piece or key 9 at each end, the function and advantage of which will be hereinafter apparent.

lin order to prevent persons without authority from operating the valve 'and stealing the automobile, l provide a two-part shell or casing 10 which as shown, consists of identically formed shell halves, each being in the form of a cylinder 11 having a closed outer end 12 and an open inner end 13. The closed end 12 of each halt is provided with an opening or key slot 1li so that upon assembly as in Figures 1 and 2,

the linger-pieces or keys 9 will each snugly l t in a slot, thereby preventing turning of the valve if by any chance a vperson should break away the central portion of either end of the shell. llt is obvious that the key being fitted in a slot at the other end it is still impossible to operate the valve. The meeting races of the'two halves are provided with recesses or depressions 15 which perinit the parts to straddle the branches ot the valve coupling and entirely enclose the body portion.

Fach halt of the casing is provided with a pair of diametrically oppositely disposed legs 16 which are slightly longer than the cylinder body. A pair of alined openings 17 is formed in the legs to permit the insertion of the shackle 18 of a lock 19 as shown in Figures 1 and 2. 'llhe inner ends of the legs 16 are continued to the bottom or closed end ot the cylinder forming ribs 20 which snugly fit in between the branches of the coupling and against the valve body, thus preventing turning of the shell when in locked position. lt is understood that the cylinders and legs are integrally formed as by casting in a unit. @bviously the palr of legs on one cylinder are arranged at right angles to the other pair and formed in the cylinder ends at points near the wall midway between the legs are openings 21 in which the legs tit.

Upon turning the valve to the position shown in Figure 3, the Huel supply is cut oil and the housing or shell halves are placed around the valve body, the keys or finger pieces 9 'being projected slightly through the slots 14 in the cylinder ends or if preferred may be'entirely covered by the shell through elimination of the slots. this position the ends of the legs 16 project through the ends of the cylinders thereby permitting insertion of the lock shackles into the openings in the legs.

This completes the locking operation and the parts are now positioned so that both locks or shell halves must be broken before the control valve can be operated.

Manifestly certain minor changes in the structural details may be resorted to and such of these changes as fall within the scope of the appended claims, I consider within the spirit of my invent-ion.

AI claim: v

l. In an automobile lock, the combination of a valve arranged in the fuel supply' line, a two-part housing for the valve, a pair of legs carried by each part of the housing, each part having openings, and said legs being adapted to be received in the openings and means to lock the legs in said openlngs.

2. In an automobile lock, the combination of a valve arranged in the fuel supply line, a finger piece carried by the valve, a twopart interlockable housing adapted to enclose the valve, and said housing having a slot to snugly receive the finger piece to prevent relative movement therebetween.

3. In an automobile lock, the combination of a valve arranged in the fuel supply line, a pair of operating finger pieces carried by the valve, a two-part interockable housing ,Y for the valve, and connection between the housing-and finger pieces to prevent relative shifting of position.

y ture.

4. In an automobile lock, the combination locking the legs iny the openings.

5. In an automobile lock, the combination of a valve arranged in the fuel supply line, a two-part housing'for the valve, each part having a pair of diametrica ly opposed parallel legs,

each part of the housing having spaced openings to receive the legs of the other part, and shoulders said pairs of legs being rela-4 tively at right angles,

arranged upon the inner face of each hous- Fing part as .extensions of said legs, and

adapted to snugly lit against the valve body Iand means for locking the legs in the openlngs.

6r In an automobile lock, the combination of a three-way valve arranged in the fuel supply line, anl operating finger piece at each end of the valve, a two-part housing for the valve, each part having a slot to receive a linger piece, a pair of spaced parallel legs carried by each part and having alined openings near the, ends, each part having openings to receive the legs of the other part, locksarranged to connect `each pair of legs upon the outside of the housing,

'and ribs formed uponv the inner faces of the housing parts to snugly' engage the wiLLIAM F. revisori'.
